LISA and the Global Analysis of Galactic Binary Gravitational Wave Signals

Explore the global analysis of galactic binary gravitational wave signals in this 27-minute conference talk by Kristen Lackeos from the Max Planck Institute for Radio Astronomy. Delve into the challenges and techniques of extracting overlapping galactic signals using the Laser Interferometer Space Antenna (LISA). Learn about the 'GBMCMC' pipeline for global fitting of Galactic white dwarf binaries and its application to simulated data from LISA Data Challenges. Discover the post-analysis and science of resulting catalog data, methods to quantify pipeline search efficacy, and future developments towards global fitting of multiple gravitational wave source types. Gain insights into LISA's capabilities, the dominance of ultra-compact binary signals in the milli-Hertz frequency band, and the complexities of resolving individual sources from the galactic foreground.
